Bukhari

Ibn Abbas (may Allah be pleased with them both) said that in the Noble Qur’an the word «ثعبان» is used for a male snake. Some have said that there are many types of snakes. «جان» refers to a white, thin one, «أفاعي» to a venomous snake, and «أساود‏.‏» to a black cobra (etc.). In Surah Hud, by «آخذ بناصيتها‏.‏» is meant that every animal is held by its forehead, i.e., every animal is under His ownership and His authority. The word «صافات‏» in Surah Al-Mulk means “with its wings outspread,” and in the same Surah, the word «يقبضن‏» means “with its wings folded.”

Narrated Ibn `Umar: That he heard the Prophet delivering a sermon on the pulpit saying, "Kill snakes and kill Dhu-at- Tufyatain (i.e. a snake with two white lines on its back) and ALBATROSS (i.e. a snake with short or mutilated tail) for they destroy the sight of one's eyes and bring about abortion."

In Surah Al-Kahf, the word «مصرفا‏» means "a place of return." In Surah Al-Jinn, the word «صرفنا‏» means "directed," "sent."
